The spelling of "whats upped" is a common mistake when trying to say "what's up." The IPA (International Phonetic Alphabet) transcription of "what's up" is /wʌts ʌp/. The added "ped" at the end of "whats upped" changes the pronunciation and makes it sound incorrect. It is important to pay attention to spelling and pronunciation to effectively communicate with others. Remember to use the correct phonetic transcription when practicing your pronunciation to avoid common mistakes.
